Just keeping hitting him with cr.mp or cr.rh if he’s spaming electricity. It will be a boring match but you will win. I know its frustrating and boring when its like that but whatever. My buddy has the same plan with anyone he plays. Cross you up no matter what. I’ll punish him over and over with ex cross counter/cross counter but no matter what he’ll keep doing the same thing.
Try doing nuetral jump with m.p when he jumps in for a hk. That works if he is not in range for you to aa with s.mp.
